Mixing silo

Homogeneous. Precise. Process-reliable.

Mixing silos from Eichholz Silo & Anlagenbau GmbH combine storage and homogenisation in a single system. They ensure that bulk materials are always mixed homogeneously, free-flowing and ready for processing. Perfect for industries with high quality requirements.

Our mixing systems – the right solution for every bulk material

Variant 1: Mechanical mixing screw

The vertically installed mixing screw ensures maximum mixing accuracy with particularly gentle product handling.

Open or closed design
Suitable for sensitive, fine-grained or homogeneous mixing tasks
Available as an internal or external silo
Volume range: 5 m³ – 120 m³

This variant offers controlled, intensive mixing – ideal when optimum homogeneity with short mixing times is crucial.

Variant 2: Static mixing tube

In mixing silos with a central mixing tube, homogenisation is achieved through intelligent stratification and extraction:

Different batches that are filled in succession are discharged again in mixed order via openings in the mixing tube
Particularly suitable for continuous processes and frequently changing batches
Very low maintenance, as there are no moving mixing elements (static mixer)

This technology ensures reliable mixing solely through material flow and gravity – ideal for robust, low-maintenance processes.

Variant 3: Static mixing cone

Mixing takes place through the simultaneous flow of material from different silo areas.

No moving parts, therefore extremely low maintenance
Suitable for large storage quantities and varying bulk materials
Volume range (mixing pipe/mixing cone): 10 m³ – 400 m³

This variant uses targeted flow paths to produce a homogeneous mixture – ideal for large silos and robust bulk materials.

Vibration level switch with fork-shaped sensor.

Silo pilot

Electromechanical system for level measurement by lowering a sensing weight.

Radar sensor

Non-contact device for continuous level measurement.

Load cells

Non-contact measuring system based on weight detection.

Pressure relief valve

Ensures pressure equalization in case of overpressure or vacuum in the silo.

Filter

For dedusting conveying air.

Flashlight & horn

Provides visual and acoustic status signaling.

Temperature sensor

Temperature measurement in storage systems.

Grounding cable

Dissipates static charge from the product.

Moisture sensor

Measures moisture content in the product.

Bursting discs

Serve as a predetermined breaking point in case of a dust explosion in the silo.

Vibrating hopper

Discharge assistance through vibration.

Mixing hopper

Used for homogenizing products.

VibraPads

Discharge assistance through vibration and air injection.

Insulation

Protection against weather-related influences.

Platform

Provides access to inspection openings for side-mounted installations.

Sprinkling system

Prevents fire load from the building spreading to the silo.

Anti-honk cone

Use of one or more anti-hup cones reduces friction and vibration on the silo body.

Axial compensator

Used in pipelines to compensate for movement, stress, and vibration.

Manhole

Side access in the silo cylinder.

Screw conveyor

Mechanical conveying device for bulk materials.

Dry air system

Maintains a dry air layer in the headspace and prevents moisture ingress from ambient air.

Sampling device

Pinch valve

Shut-off device in the silo filling line. In combination with a pressure sensor, it can stop the filling process if the conveying pressure is too high.

Feed pan

Transfer point between material flow and air flow.

Suction pot

Connection point for vacuum material conveying.
